larlyt'ofmeans for preventing displacement of the nuts emr e inetallic pins of insulatea-refer positionf onjthe cross arm of a teleoifteleplron e or other suitable sup I theiinvention is to provide 'aldcking washer designcd to be positioned betwee the nut and cross arm or other support'and having in tegral attaching spurs d 'to pier'cdthe cross arm when the on the threaded pin or bolt.

fi hefobjeet'f isto provide a washer havii' gf oppositel y flfdisposed locking ears adaptd'f 'to be bentj"'laterally into engagemerit w n the adjacent walls of the nut, said 'g'"provided with terminal depression concavitiesfor the reception of a tool thereby toassist' bending said ears in engagement with the nut. y

-' A furt'her object to provide a washer having slits extending inwardly on each side of the; locking ears whereby said ears may be teatime-en gement with nuts of different s'i'ze'andsha es,

A still furt er obj ect of the invention is to 3 5 generallynn rove this class of devices so as to increase t ieir utility, durability and efficiency.

Withthese and other ob ects 111 view the invention consists in the construction and- 0 novel combinatlon and arrangement of parts hereinafter-fully described, and illustrated in the accompanying drawings, it being understood that. various changes in form, proportions and minor details of construction 5 may be resorted to within the scope of the ap ended claims.

taching pin of an insulator. Fig. 4 is a erspeetive view of the washer detached. *ig. 5 is a longitudinal sectional view illust ating a modified form of the invention.

Similar numerals of reference indicate corresponding parts in all of the figures of the t 1e pin 5, said washer being interposed between the cross arm 6 and nut 9, asbest shown in Fig. 3 of the drawings. The body portion 7 is provided with laterally extending attaching spurs 10 adapted to be bent at an angle to the adjacent surface of the body ortion '7 so that when the nut 9 is 'adjuste on the pin the spurs will be driven into the wood instituting the cross arm 6 and thus lock the washer in position on said cross arm. Attention is here called to the fact that the piercing points 11 of the spurs 10 are deflect ed inwardly toward the bolt-receiving opening 8 so that when the spurs are driven into the support 6 they will firmly grip the fiber of the wood to form in efi'ec-t a locklng key.

Extendingdaterally from opposite sides of the circular body portion 7 and referably disposed at right angles to the attacliing spurs 10 are looking ears 12 adaptedto be bent laterally into engagement withthe side walls of the nut 9, the terminals of said ears being provided with depressions or concavities 13 adapted to receive the point of a suitable tool so that said ears may be conveniently bent laterally into engagement with the nut. The depressions 13 not only serve to receive the point of the tool when bending the looking ears to operative position but also form spring locking lips 14 which bear against and bite into the side walls of the nut thus serving to prevent accidental rotation of said nut.

Extending inwardly from the opposite sides of the body portion 7 at the ears. 12 are parallel slits 15, the object of which is to permit the ears to be bent into en agement with nuts of different sizes and s apes. When the washer isus'ed in connection with a standthen-bent laterally into engagement with the sides of the nut by introducing the point of a chisel, screw-driver or other tool within the depressions 13 and pressing laterally'onsaid tool thus locking the ears in enga er'nent with the sides of the nuts and effectua ly preventing accidental rotation of the latter.

In Fig. 5 of the drawings, there is illustrated a modified form of the invention in which the attaching spurs .or lugs 18 are preferably stamped or struck upfrom'the body of the washer, *the device, beingotherwise similar 1n construction 'tothe washer'shown in Fig. 1 of the drawings If desired, however, the lugs 11 may also be used in connection with thisform of the device and by way of illustration said lugs are indicated at. 11.

When the washer is usedin connection-with a metallic surface such as a fish' plate, suitable openings or depressions may be formedin the fish plate for the reception of correspondingly shaped depressions formed in the washer.

While the device is principally designed for use in connection with the metallic pins of insulators, it is obvious that the same may'be used with equally good'results on-the clamping nuts of rail joints, bridge joints or for wagon work,tcar building, or wherever a device of this kind is found desirable.

Having thus described the invention what is claimed is: i

1. The combination with a support having a bolt extended there-through and providedwith a clamping nut, of a washer interposed between the nut and support and provided with attaching spurs adapted. to pierce the support, oppositely disposed ears formed integral with the washer and provided with terminal depressions defining" inwardly extending spring locking lips adapted to bear against the sides of the nut, there being slits formed in the washer oneach side of the lockmg ears 11d connected by transverse weakening grooves thereby to permit the ears to be bent laterally into engagement with the nut.

, 2. The combination with a support having a bolt extended there-through and provided with a clamping nut, of awasher interposed between the nut and support and provided ing said slits at the juncture of the ears with the washer. I l

3. As" an article of manufacture, a washer formed of a single piece-of metal having a bolt-receiving opening formed therein and provided with oppositely disp= sed locking ears the terminals of which are provided with depressions defining spring locking lips, there being slits extending'i'nwardly from the peripheral edge of the washer at said locking ears, a transverse weakening 'oove connecting said slits at the base of said ears, and attaching spurs disposed at an angle to one face of the plate and extending in-a direction opp0site the loekin ears.

In testimony t fat I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
